Specification of Letters Patent.

Serial No. 602,155.

To all whom it may concern employed with good results in the purifica Be it known that I, J ACQUES VVITTLIN, ation and deodomZation of the'crude cresols, subject of the Emperor of Austria-Hui'igary, either alone or in conjunction with the caland a resident of Vienna, AustriaI-lu'ngary, clum oxid.

have invented certain Improvements in the- The cresols purified and deodorized ac- Manut'acture of Antiseptics, of Which the cording to my invention are capable ofbeing following is a specification.

This invention relates to certain improvements in the manufacture of antiseptics, an more particularly in that class of antiseptlcs which involve the use of cresols, either alone,

a much Wider field than is possible in the case of ordinary crude cresols, whose strong and offensive odor greatly availability, or when desired, the cresols purified and deodorized as above described may be admixed or combined with various other substances for accentuating their germicidal or antiseptic properties, or rendering them better adapted for certain special applications. For example, the cresol purifie and deodorized accordin to my invention may be dissolved in or a mixed with about twice its Weight of soap solution or emulsion, after vyhich the addition of about 0.2 per cent. picrio acid; 0.02 er cent, chlorpicrine,

the invention is, in part, to purify and modity the evil odor commonly possessed by crude cresols, so as to widen the field of usefulness of the 'antiseptics prepared therefrom, and in part, by admixture of such purified cresols with other substances, to produce a resultant compound or mixture intectant properties as are calculated to iman antiseptic.

1 have ascertained that the ofiensive odor of crude cresols is attributable largely to the presence of certain sulfur compounds which pass over with the cresols at the high temperatures at which such substances are separated from the tars wherein they are contained, and one part of my present inventionconsists in subjecting the crude cresols containing such sulfur impurities, to the action of certain reagents, such for example, asmetallic oxids and'superoxids, which are particularly suited for the separation or remoral of such sulfurimpurities, and which leave the product possessed only of the hat ural faint odor of pure cresols. I

In carrying out this part of my invention in practice, good results may be attained by subjectingthe crude cresols to the action 0 milk of lime or other liquid containing about per cent. of calcium oxid, whereby the malodorous constituents of the cresols under treatment are caused to combine with the lime or to be taken up thereby and precipitated,'leaving the cresolsin a purified state only of the faint odor character istic of these bodies when in a state of comparative purity. Certain superoxids, an

the iron-containing byroducts used in or resulting from gas reningor purifying processes may also be septic or disinfectant of great efliciency posno offensive odor.- The antiseptic thus prepared is non-explosive and much-more efficacious than phenol or picric acid by reason of the operation of the chlorin in freeing or weakening the bonds of the NO, groups.

If desired about 0.01 zol, or equivalent scenting ingredient may be incorporated in the preparation of the antiseptic. The antiseptic prepared in this manner may be readily diluted to such strength as will fit it for difierent uses.

VVher'e it is desired to prepare antiseptics in this manner by the use of cresols with or Without the admixture or combination of present invention further contemplates the mcorporation of ammonium fiuorid equivalent fluorin-containing salts or fiuorin compounds in the preparation of the antiseptic, whereby the germicidal or disinfect-' ant properties thereof are Very materially increased.

In carrying out this part of in practice, about 0.4 per cent. of ammoniun'r fluorid may be admixed orcombined 'with the ingredients above enumerated with the result ofvery greatly augmenting the efiici'enc of the preparation, and if the cresol entering into the preparation be purified or reduces their and 5 per cent. formalin will afiord an anti per cent. nitrobenmy invention sessed of no irritating properties and having I claim and d Correction in Letters Patent No. 1 ,044,84 0.
